GAS-MACHINE.

SPECIFICATION forming part of Letters Patent-N0. 791 ,33t, dated May 30,1905.

Application filed June 1, l903. Serial No. 159,613.

following is a specification.

The purpose of this invention is to generate gas for immediateconsumption, either for heating or lighting, and to combine with themachine means for automatically regulating .the supply of gas to thegenerator-burner according to the pressure within the tank or reservoircontaining the gas-producing medium.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of .the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figure1 is a perspective view of a gas-machine embodying the invention. Fig. 2is a detail section through the mixing-chamber and the parts directlyconnected thereto. Fig. 3 is a detail view showing the maindistributing-pipe, the auxiliary pipe connected thereto for supplyinggas to the generatorburner, and the pressure-regulator connected withthe valve of said auxiliary pipe for controlling the supply of gas tothe generatorburner proportionately to the pressure within the tank orreservoir containing the hydrocarbon, said pipes and mixer being insection. Fig. 4 is a horizontal section through the mixing-chamber.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The tank or reservoir 1 may be of any construction and capacityaccording to the number of lights for which the machine is designed, andsaid tank may be arranged in any convenient position.

The gasolene or other volatile hydrocarbon employed for producing gas issupplied to the tank or reservoir through an opening, its top sideclosed by cap or screwplug 2. Valve 3 is fitted to the upper portion ofthe tank or reservoir and is adapted to have an air-pump or otherpressure-creating device connected thereto for charging the tank orreservoir with air under pressure, whereby the hydrocarbon may be forcedtherefrom into the generator against any tendency of back pressure.

The generator 4 is located at any convenient point, so as to receive asupply of hydrocarbon or gas-producing medium from tank or reservoir-1,with which itisconnected by means of pipe 5, the latter communicatingwith the bottom portion of the tank, so as to insure receiving a supplytherefrom. The generator 4 may be of any structural type commonlyemployed in machines of this variety or any hydrocarbon-burners and isheated to the proper temperature by burner 6, same being of annular formand encircling the generator. In order to utilize a maximum peroentageofheat from burner 6, the upper portion of generator 4 is provided with aspreader 7, overhanging burner 6 and receiving the whole effect of theflame from said burner and directing same outward. Valve 8 is connectedwith generator 4 and is controlled by stem or rod 9 and opens into anend portion of mixing-chamber 10. A second. valve 11 is similarlyconnected .to generator 4: and is controlled by stem or rod 12 and alsocommunicates with mixing-chamber 10. Ohviously any number of valves maybe connected with the generator according to the desired number ofdistributing-pipes, so that the gas may be shut off from any one of thedistributing-pipes without affecting the lights supplied by means of theremaining distributing pipe or pipes.

The mixing-chamber 10 is located above the generator 4: and valves 8 and11 and may be of any size and shape, according to the general design ofthe machine. As shown, the mixing-chamber is approximately of box formand is open at its ends, same being covered by Wire-gauze or in anysimilar way to freely admit air for admixture with. the gas prior toentering the distributing pipe or pipes. As shown, two pipes 13 and ltare connected with the mixing-chamber and extend into same to within ashort distance of the respective needle-valves 8 and 11 and carry thegas to the required point of use. The pipe 13 is the maindistributing-pipe, whereas pipe 14 is used only when isolated burnersare to be lighted either for illuminating or heating purposes. .Anauxiliary pipe 15 connects at its upper end with main distributing-pipe13 and at its lower end with pipe 16, having connection withgenerator-burner 6 for supplying gas thereto. Auxiliary pipe 15 isprovided with valve 17 to admit of controlling the supply of gas to saidburner as may be required, same being governed by pressure within tankor reservoir 1. Pressure-gage 18 of any make or pattern is connectedwith the upper portion of tank or reservoir 1 by means of the pipes (band b, and its arm 19 is conneeted with the stem 20 of valve 17, wherebythe latter is opened more or less, according to the degree of pressurewithin tank or reservoir, same being determined by proper tests. In thismanner the supply of gas to burner 6 is regulated.

The pipe 6 is shown extended and is connected at its outer end to thegenerator 4:, but without communicating therewith. The pipe 16 connectsthe burner 6 with the tank 1, but is not in eommnication with the tank.The pipes b and 16 are utilized as convenient means for bracing thegenerator, but do not establish communication between the tank and thesaid generator or burner.

A burner 21 is connected by pipe 22 with the upper portion of tank orreservoir 1 and is arranged to direct a jet of flame against generator 4when heating same preliminary to starting the machine. After thegenerator has been sufficiently heated to convert the hydrocarbon intogas a portion of same may pass to burner 6 through pipes 15 and 16, atwhich time burner 21 is closed, the generator being maintained at theproper temperature by burner 6. As the pressure varies within tank orreservoir 1 valve 17 will be opened more or less, thereby regulating theflame of burner 6, so as to generate a greater or less quantity of gas.

hen the machine is in operation, the gas from generator 1 passes throughvalve 8 into mixing-chamber 10, thence into main distributing-pipe 13 tosupply the burners connected therewith. In the event of it beingrequired to light one or more burners connected with the supplementaldistributing-pipe 14: valve 11 is opened, thereby permitting a portionof the gas to pass from generator into mixingchamberand thence into pipe14, as will be readily comprehended.

Having thus described the invention, what is claimed as new is- Agas-machine comprising the following elements combined, arranged andoperating in the manner set forth, v (1., a tank containing ahydrocarbon and provided with means for attachment thereto of anair-compressor, a vertical generator, a pipe connecting the lower end ofthe generator with the bottom part of the tank, a burner near the upperend of the generator, a horizontal mixing-chamber open at its ends andconnected at a central point with the generator and having valves nearits ends in connminication with the upper portion of the generator,distributing-pipes attached to the side of the mixingchamber opposite tothat provided with the valves and in line therewith, brace-pipe16between said tank and burner and in communication with the latter, only,pipe 15 in communieation with a distributing-pipe and the brace-pipe 16,a valve 17 in the pipe 15, bracepipeZ) between the tank and burner andin communication with the tank, only, a pressure-gage in communicationwith brace-pipe b and connected with valve 17 for controlling the supplyof gas to the burner by means of variation in the pressure within thetank, and a burner 21 connected with the upper portion of the tank andarranged to direct a flame against the generator.

In testimony whereof Iafiix my signature in presence of two witnesses.

JOHN HENRY ESKER.
